I'm sorry you didn't realize but the advertised features are, on launch.
Lets be very clear about this. On release, the wallet will include trading support, coin mixing, pool mining, dice game and a marketplace. Which is all very nice... and then there is a host of other juicy "future goals" that you plan on achieving. But you want the IPO money released upfront and is not ready to accept the payment in parts as and when those goals are implemented? And you also think this is not in the least scammy looking because you are giving them "EdgeCoins" in exchange for BTC through an escrow?
A Developer who is planning to be there for the long haul and actually plans on implementing the promised features would have absolutely no problems in having the BTC released from escrow as and when the features are ready. On the other hand, for someone who has no plans of doing any of that will insist on having the valuable BTC released in exchange for the premine that he pulled from thin air.
As long as people realize that the coins they hold are nothing special and are worthless shitcoins till you implement the features, its all cool. They're also trusting you to follow through AFTER payment, and that the escrow is just to mediate the transfer of funds, and has nothing to do with whether the features will be implemented or not. As long as someone who plans on "investing" in this coin is clear of these unmentioned details, they are free to make or lose money with the informed decisions they make. The only reason I insist on spamming is because this clarity is not available in the OP.
